Uses Schedule #: 0
0 = Internal Clock
1-7 = External Clock
The CVAHU normally uses its own Real Time Clock and an
Internal Week Schedule to determine the
Occupied/Unoccupied mode of operation. The CVAHU does
have the ability to use a Global Broadcast from another
scheduling device on the communications loop if a more
powerful schedule is required. If an external schedule is used,
the range of schedule numbers is one to seven.
